As I run
sudo DOWNGRADE_FROM_ALA=1 downgrade firefox
I got the version which I currently have installed (the one marked with the + sign) and furthermore the important Firefox 80 which still I don’t have available (the one which I marked with the red highlighter)
Firefox 80 will include, finally, HW acceleration on X11!
Would be the case, so, to push Firefox 80 to all branches, also for the sake of bug haunting?
Since a long time, when I want to play HTML5 videos on Firefox on Linux, I rely on MPV  which gave, also on 4K videos, a really light usage of CPU;
(otherwise, when I play videos from Firefox itself - on Linux -, I got almost 80% - 100% CPU usage); furthermore I experienced, here and there, stuttering while scrolling (please notice that: I have “
layers.omtp.enabled” set to
true and also “
gfx.webrender.all” set to
in facts, when I run the bencharmk HTML5 Fish Bowl I always got 60 FPS. But without real HW acceleration: and Firefox eats a lot of CPU usage (100%)
However: many thanks to Manjaro’s Team: I’m on the stable branch and for me is OK to wait
